Durlon® Durtec®

Durlon® Durtec® with Durcore® gaskets are made with a specially engineered corrugated metal core that is bonded on both sides with soft covering layers, typically flexible graphite. The core is produced by patented technology that allows the finished gasket to have the best possible mechanical support function. Corrugations in the Durtec® core are virtually un-crushable unlike conventional corrugated metal core gaskets. The precision construction guarantees that Durlon® Durtec® with Durcore® gaskets will have excellent sealing characteristics even under low bolt loads.

The Durtec® gasket is designed to withstand high temperatures and pressures, to be blowout resistant, to be fire safe, and to resist toxic and or corrosive chemicals for such applications as: pipeline flanges, valves, small & large pressure vessels, heat exchangers, towers and tanks.
Gaskets made with specially engineered DurCore® (corrugated metal core) technology that is bonded on both sides with soft covering layers, typically oxygen-inhibited flexible graphite or Durlon® 9600 ePTFE facing. The core is produced by proprietary technology that allows the finished gasket to have the best possible mechanical support function. Corrugations in the Durlon® DurCore® are virtually uncrushable unlike conventional corrugated metal core gaskets. The precision construction guarantees that Durlon® Durtec® gaskets will have excellent sealing characteristics even under low bolt loads. The Durlon® Durtec® with ePTFE (Durlon® 9600) Facing - 
Able to withstand the demands of high vibration, aggressive chemicals and cyclic conditions - Suitable for use in pulp & paper applications and as a replacement for low stress spiral wound gaskets - Conforms well to damaged flange faces
